An arrest warrant was issued on Wednesday against Manorama Devi for keeping liquor in her home in Gaya town against the prohibition law and for harbouring her fugitive son who has since been arrested, a police official said.

Her bail plea is scheduled to be heard on Monday, the official said.

The legislator, who was suspended from the ruling Janata Dal-United (JD-U) on Tuesday, has been evading arrest.

Her son Rocky Yadav was arrested on Tuesday from a house in Bodh Gaya for allegedly killing on May 7 Aditya Sachdeva, the teenaged son of a Gaya-based businessman, and has been remanded in police custody.

Manorma Devi’s husband Bindi Yadav, a criminal turned politician, has also been arrested in connection with the killing of the teenager.

Aditya’s family has demanded a CBI probe into the case and speedy trial to ensure justice for them.

With Bihar Chief Minister Nitish Kumar asserting that no guilty will be spared, the police promised to file a charge sheet within a month.

Additional Director General of Police (Headquarters) Sunil Kumar said: “Police have been working to complete investigations in the case within three weeks. The charge sheet will be filed within a month to ensure speedy trial.”
